The score of a statistics problem is normally distributed with μ=80.9 and σ=8.4 NOTE: Assume for the sake of this problem that the score is a continuous variable. A score can thus take on any value on the continuum. (In real life, scores are often treated as if they were continuous values but are actually discrete in most cases.)
